Pineocytoma, also known as a pinealocytoma, is a benign, slowly growing tumor of the pineal gland. Unlike the similar condition pineal gland cyst, it is uncommon.

Diagnosis[edit]

Pineocytomas are diagnosed from tissue, i.e. a brain biopsy.

They consist of:

Pineocytomatous/neurocytic rosettes are superficially similar to Homer-Wright rosettes; however, they differ from Homer-Wright rosettes as they have (1) more neuropil at centre of the rosette and, (2) the edge of neuropil meshwork irregular/undulating.
